Abstract
A fingerprint sample input apparatus, a fingerprint verification device, a method for aligning fingerprint samples, and a method for fingerprint verification are disclosed. The fingerprint sample input apparatus comprises fingerprint reader, receiver for public part of fingerprint template, alignment matcher, matrix generator, and transmitter. The fingerprint verification device comprises memory, transmitter, receiver, processor, matrix comparator, and threshold comparator. The method for aligning fingerprint sample comprises reading fingerprint sample, receiving a public part of fingerprint template, searching for and determining a matching position between the sample and template, generating an aligned spectral data matrix, and sending it to a fingerprint verification device. The method for fingerprint verification comprises sending a public part of template, receiving an aligned spectral data matrix, determining matrix difference between a spectral template matrix and the aligned spectral data matrix, comparing the matrix difference with a threshold, and outputting a result.
